U20 General Discussion / Re: What electronics being used and liked?
« Last post by David Krausz on April 17, 2022, 08:21:18 PM »
U20 Class Rules (2020) state "GPS based devices may be used only to measure speed and indicate heading, and marking (pinging)
the starting line during One Design class racing. Fully functioning GPS based devices may be used for all
other types of racing"

With boats now allowed to using pinging, what brand and model of electronics are you now using? Would you change if you could do it again? Where did you mount it?  Did you have to build a custom bracket? Any photos?

U20 General Discussion / Official class logo file
« Last post by Gray Shannahan on April 17, 2022, 01:59:23 AM »
Iím looking to replace the class logo on the hull. Mine is old and worn and Iím about to change the name and want to give the boat a fresh look. Does anyone have the logo file?
Hereís a pic of what Iím asking about:
Keel Repair - Richard Hunt

Bayview had this problem with all six boats You can grind out the keel box two ways 1. drop the keel out of the box using a crane 2. take the keel plate off put the boat in the water and lower the keel out of the way (not to far) Dremel works great to grind out the cracks , clean out all the debris I used Epoxy with 406 adhesive filler to fill the cracks, a syringe is helpful to inject into the cracks then put 2" tape over the cracks to keep the epoxy in place and the sanding to a minimum. Then spray a little gelcoat over that for looks I also put 10 thought bolts in the keel box (5 a side) ,the pictures I sent show 4 total around the wedge area of the box ,these are old photos. 5 bolts a side help keep the keelbox from moving or flexing , epoxy does not like to flex . In photo 001 you can see the bolts going thought to the G-10 which is a good backing plate to hold the keel box together I did countersink the bolts Drill the holes for the keel bolts first before you epoxy the cracks The epoxy putty USI uses is ok it works . but even a boat that sees very little use will eventually leak into the air tight compartment I will take some more pictures if any body would like to see the 10 bolt system Richard Hunt.

Tools and materials mentioned in the webinar:

Tool for cutting out the old caulk/putty is an Oscillating Saw.  Made by Fein or other vendors.

3M 5200 - Super strong adhesive, sealant caulk.  Do not use in applications where you want it to come apart in the future:

U20 General Discussion / U20 Class Member Webinars #3 U20 Maintenance

Hello everyone,

Here is a recording of the 3rd webinar on U20 Maintenance.  Be sure to add your thoughts to the Maintenance forum!

I find these webinars very interesting and helpful.   What a great opportunity to share thoughts and experiences.  Especially for me because I have not been able to join any of the class races.  I was quite impressed with the knowledge and experience in the group.  Thanks to everyone for putting this on and participating.

Last evenings webinar on maintenance was no exception.  Naturally, I thought of more questions after it was over.  e.g How do you fix a crack under the floorboards between the flange and the inner side of the hull?   There used to be hardware that would allow you to adjust the turnbuckles on the stays without additional tools.   Is that still available?  ...

I hope you will continue these in the future.   One topic might be boat modifications or variations that people have implemented, such as lifeline straps, turnbuckle adjustment, main sheet and boom vang rigging. As someone who does a lot of single-handed sailing, I am always looking for new ideas to have more control and fun on the water.  I would also be interested in a webinar based on the carbon mast. e.g., what it takes to convert, costs (including conversion of stays, sails, etc) how to go about doing it, advantages, disadvantages.  Is everyone happy they made the change?  I would also be curious if anyone has done roller furling on the boom with this, and if so, how well did it work?

The U20 has been a great boat for me.  The class, this forum, and these webinars make it even better.   Thanks again for all of your work to make these possible.

U20 Boat Maintenance & Care / Keel box repair at Elkhorn Composites
« Last post by Bob Comstock on April 13, 2022, 01:01:31 AM »
Due to repeated collisions with underwater rocks, my flange had separated from the keel box and a crack was visible on both sides of the keel.  Water was leaking into the inside tank during the summer when the boat is sailed often. 

Per Craig Smith's direction, I removed the putty from the flange gap with a buzzy tool (same as used for drywall and general vibratory cutting).  I then applied masking tape around the area to be repaired to ensure I didn't get epoxy outside of the desired area.  I used a putty knife to repeatedly push toughened epoxy (ask Craig for the correct product) into the gap and then smooth the inside surface (adjacent to the keel).  After curing, I filed and then sanded the epoxy to match the keel box.  The entire repair took two days.

Should no shortly. Repair even through Elkhorn is likely to be your best option.  One of our local boats sent his there and Craid did a great job with it. Looked brand new.
